Newspaper publisher Tronc has had a rocky few months. Plagued by management shakeups, unionization battles, layoffs and accusations of sexual harassment, the media group formerly known as Tribune Publishing has struggled in its efforts to adapt to a digital landscape.

Why it matters: An underwhelming year-end earnings report further sounded the alarm for Tronc investors earlier this month, causing the company to lose almost a quarter of its market value in a single trading session.
